To all whom it my concern:

Be it known that I, Ennnn W. Dunrns, a citizen of the, United States, residing at Bingham Canyon, in the county of SaltLakc and State of Utah, have invented new and useful Improvements in Mucking-Machincs, of which the following is a specification.

My invention relates to an apparatus which is designed to excavate and transfer ore, earth or material capable of being thus transferred, such machines being known technically as mucking machines.

My invention consists in the combination of parts, and in details of construction which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 is a side elevation. Fig; 2 is a pla view. Fig. 3 is a partial side elevation in section. Fig.4 is s. transverse section. Fig. 5 is a side elevation of a part of the apparatus. Fig. 6 is a plan view of frame 15.

-It is the object of my invention'to provide a substantially automatic apparatus by which'matcrial may be excavated by the forward movement of a bucket, then elevated and carried rearwardly to a point where the bucket may be dumped or discharged into a. suitable receptacle. For the purpose of conveniently carrying out this operation I employ a truck as at A mounted upon suitable wheels and adapted to travel upon a track as at A so that the truck A may be advanced as required toward the pile of material which is to be excavatcd, and this truck carries the excavating apparatus. Upon the truck is mounted a frame 2, and upon the upper ends of the diverging arms of this frame is secured a track 3 which is shown substantially parallel with the track A. i

The excavating bucket 4 is operated with relation to the truck and frame as follows: The bucket is connected by an arm 5 with the lower part of a traveling frame 6; this arm being pivoted or fulcrumed as shown at 7. This traveling frame 6 is fixed to and supported by a 'frame 11 rcciprocable upon the itrack 3,by means of rollers 8 which are journalcd ingyokes or hangers, as shown plainly in section Fig. 4, rind rest upon the upturned edges of the rails 3. 'T frame ll and the bucket frame with it, are capsbiFof being moved forward and back with relation to t e truck and frame 2, as will be hereafter described. ;Supported uponthe horizontal portion of theanglc irori track 3, are cylinders 1) having their axes parallel with the track and the line piston-rods 17 extending through the cylinder-headsand connecting with the cross-bar 15. The crossbar 15 to which the ropes connect, is in line with the piston-rods and the axes of the cylinders 16 and are connectcd with the longitudinal bars of the frame 15 by hangers 15 and diagonal brace rods 15". The frame 15 is slid-able in guides 21 which are supported from the frame 11 as shown in Figs. 4 and 5 The movement of this frame and cross-bar serves to raise the bucket 4 after it has been filled, and to transfer it to its dumping or discharge position.

The fluid which is most convenient to be employed is compressed air which may be admitted through a pipe or how 18 from any source of supply, and this supply pipe connects through cocks or valves 19 and 20 with supply pipes 21 and 22 through which air is admitted respectively to the cylinders 9 and 16, these cocks being under the control of an operator.

The operation of the apparatus as far as described is as follows: The truck A having been advanced upon its track A to a point as near the pile of material as is convenient, remains in a stationary position, and fluid pressure being admitted into the cylinders 9, will, through the piston and piston-rod, advance the frame 1l-with which the arms 6 form a rigid connection to carry the bucket, and the bucket having been lowered into the position shown in Fig. 1, this advance will force the bucket into the pile of material with a lifting movement until it is loaded. The reverse movement of the pistons in the cylinders 9 will then retract the bucket-carrying frame 11 until it is substantially in a position'within'the frame 2 and supportcd above the this, pulling upon the suspcnding ropes 13, will drnwthe bucket up to a point contiguous to the direction pulleys 14, the bucket moving in an arc fxom its lowest and filled position, until it reaches a point just above theaxis of the pulleys '14. A continuation of the movement of tho frame 15 then carries the bucket over the remainder of its circular travel until it has arrived at the position shown in dotted lines in Fig. 1, when -the top or cover 4." will drop open and allow the contents of the bucket to fall. Acar, not here shown, is provided to receive the. discharge from the bucket 4, this car also running upon the track A, and may be transmitted to any desired point. Connection is made between the fixed air-conducting pipes and the cylin- Provision is made for maintaining -zhe proper tension of the ropes 13 by any suitable takeup devices for the purpose. When the bucket has been dumped it is returned through its arc of travel by the admission of fluid to the opposite ends of the cylinders 16, this acting throughthe pistons and the piston-rods 17 to retract the frame 15, and when the bucket reaches its de pressed position shown in Fig. 1, the frame which carries it will then be advanced by opening the controlling valve by which. air is admitted into the cylinders 9, and the slidable flame 11 which carries the depending frame 6 to which the bucket is attached is again ad vanced to force the bucket into the material and load it. In order to return the bucket through the first part of its arc of return movement, and to a point beyond the fulcrum point of the arm 5, I have shown an arm or hanger 25 extending down from the irame 15,

to its filling position, by gravitation.

It will be understood that if it is desired to discharge the material to one side of the apparatus, the frame 2 may he turnable upon a. vertical pivot 2 connecting it with the truck A.

Having thus described my invention, what I claim and desire to secure by Letters Patent is' vl. An apparatus for truustcrring material, said apparatus consisting: of a bucket, a fulcrumed lever arm upon which the bucket is urried from an excavating to a dumping positi' iluid pressure means for advancing the bliclici to be filled while in the excavating position, and means by which the bucket is raised and inverted about the fulcrum of said lever arnr :2. in an apparatus for eiccuvatim, and transferring earth, a truck, a franw-woi ind base upon which the track is s pported at an. elevation from the base, a second framework and'rollers :miaptcd IO lravcl upon the track, a bucket carried upon millisecond frame-work, a fluid pressure mechanism and suspending cables whereby the in it may bc lowered to an excavating position, and in scd to a dumping position, unda iluid pressure mechanism by which the bin-Bic! iii advanced to be tilled while in its llK'k'lU/lli po l. in an apparatus for cxmivating and transferring material, a iieclcd base, a. truck supported at an elevation tlllilv. said base, a bucket irumc'liuving rollers traveling upon inc lmcl: I bu-"iui carried by iid frame, cylinders bavliu; llillil p ssurc actuated pistons movable parallel with the track, unblci; conr -ctin,', the bucket with the pieton-r s to w rlic bucket about its fulcrum support, other cyliinh with pistons, connections whereby the bucket is ad anced lo be tilled whil in its loading position,
